[. . . ] Do not deviate from the specified resistance, wattage, and voltage ratings. Before returning the set to the customer, always perform an AC leakage current check on the exposed metallic parts of the cabinet, such as terminals, screwheads, metal overlays, etc. to be sure that the set is safe to operate without the danger of electrical shock, Plug the AC line cord directly into a 120 V AC outlet. (Do not use a line isolation transformer during this check. ) Use an AC voltmeter with a sensitivity of 5000 ohms per volt (or more) as follows: Connect a 1500 ohms, 10 watt resistor, paralleled by a 0. 15 mfd, 150 VAC capacitor, between a known good earth ground (water pipe, conduit, etc. ) and the exposed metallic parts, one at a time. [. . . ] Video input terminals (VIDEO IN) These terminals are used to input a video signal source to this monitor. Connect to the video output of a VCR or another monitor (for loop through connection) or to a video camera. 5. Focus control (FOCUS) Turn to adjust picture focus to optimum focus. 6. Sub-brightness control (SUB-BRI) Turn to adjust picture brightness. 7. Video output terminals (VIDEO OUT) These terminals are used to output a video signal from this monitor. Loop-through output of the video in BNC connector, then connect to the video input of another monitor or a VCR. Termination Switch (HI/75 (Lo)) Select the input impedance (HI/75 ohm). When using only one monitor, turn the termination switch to the 75 ohm position. When using more than one monitor, set all of the termination switch to the monitors to the HI position. ­5­ 3 1 2 4 Fig. 4 5 67 Single Connection To Video B INPUT terminal (Video signal cable) Monitor To Video A INPUT terminal (Video signal cable) Video recorder To Video input terminal To Video input terminal Video recorder Video camera (Rear panel) Monitor Fig. 5 Coaxial cable To Video input terminal Monitor Video recorder Video camera Fig. SERVICE ADJUSTMENTS ADJUSTMENT ITEM HORIZONTAL HOLD ADJUSTMENT TIMING PATTERN SETTING VR LOCATION VR404 ADJUSTMENT PROCEDURE Turn off horizontal sync.
